Risks of using R (Ruby?) & Python

What are the risks associated with installing the above on a PC/laptop for doing data analysis?

Are the following mitigating measures valid?

a) apply regular patches for R & Python to fix vulnerabilities: as they're opensource, are the patches
               released quite timely/regularly.  I tend to think opensource is lacking in this area
b) if patches are not applied regularly, can we isolate the PCs such that they have no Internet
    access & no email clients to mitigate?  I tend to think most breaches result from Internet,
    emails activities & infected USB devices
c) is it common that emails contain malicious python attachments?
d) Where can we subscribe to  vulnerabilities news/updates for these 2 softwares?
e) Python and Ruby are dynamic platforms (free ware) , have to tighten the web application security if it’s being used for web applications, Python has flexible features that make it particularly useful for hacking?  
    Can we harden these & where to obtain such a hardening guide?

R is different from Ruby.

If you're running R, there is no issue, as that's not designed as some server language.  You'll be mainly doing statistical calculations.

If you're running Ruby, then, you may have issues, as Ruby is used by people to run servers or webserver scripts.  If you're just using it for local scripts, then you won't have quite as many issuse.

Python is just a scripting language, while you can also use it to run webserver scripts, but it's not widely used for that.  People run Python more for doing scientific calculations.

When you run R, Ruby, or Python, you'll generally run in on some unix system and the patches are usually released along with other system and 3rd party patches.  Just run the standard updates and those packages will be patched.

If you're running them on Windows, you're going to have to manually download them and update the pakages.

There's arguments : if we have VB scripts enabled, why is it Python is a concern??
sunhuxAuthor Commented:
Are there known Python vulnerabilities that have no known patches or took more than 3 months for patches to be released upon the vulnerability being publicized?  

Are malicious python scripts attached to emails prevalent?
Not sure why you're worried about Python.

Are malicious python scripts attached to emails prevalent?
No.  They generally concentrate on Windows executable files.  Python scripts would need to be packaged with python or compiled into binary executables to run.  It's not a good/easy vector because you'd have to expect that python is installed and running on the system.
